LBHL (~170 nm) UVI images of Polar satellite from December 1996 to January 1997
The UVI aboard the Polar satellite can obtain the ultraviolet auroral intensity distribution in the northern hemisphere. In order to reduce the influence of dayglow on UVI image data, we only used LBHL (~170 nm) UVI images from December 1996 to January 1997, which have full aurora oval (the aurora o...

| Summary: | The UVI aboard the Polar satellite can obtain the ultraviolet auroral intensity distribution in the northern hemisphere. In order to reduce the influence of dayglow on UVI image data, we only used LBHL (~170 nm) UVI images from December 1996 to January 1997, which have full aurora oval (the aurora oval region in the northern hemisphere during this period is in the polar night region, and the aurora image is weakly affected by dayglow and solar light). Each image has a pixel size of 200×228 and a spatial resolution of about 0.04° per pixel (UVI auroral images of Polar satellite taken at apogee have a pixel size of 40×40 km at 100 km above the ground), and the value of each pixel is converted to the value with auroral intensity, the unit is photons/cm2/s. These UVI data is save as the mat file of Matlab. |
